The exhaust fan for a toilet is silent. How to choose a bathroom fan

Maintaining the necessary level of comfort in the bathroom is a very important task. Constant humidity significantly reduces the service life finishing materials, adversely affects the appearance of sanitary equipment and mirrors, contributes to the appearance of mold and other fungi, and this negatively affects human health. Help solve all these problems bathroom hood. The exhaust fan comes in three designs: axial, centrifugal or radial.

Axial extractor in the bathroom equipped with simple impellers with an impeller and is made, as a rule, in a cylindrical body. In such a fan, the blades capture air currents and move them along the axis. Such fans are in demand due to the ease of installation and a fairly high energy efficiency. Axial models are installed in the wall, directly in the opening of the ventilation shaft.

Centrifugal bathroom hood is a relatively recent invention. These devices combine simplicity of design and ease of use, as well as high power with low noise characteristics, thanks to which they have gained incredible popularity in their short history. Installation of centrifugal fans is usually carried out in a flow ventilation system, under the ceiling. Such models can even be hidden behind plasterboard panels, which is especially important for rooms with high design requirements.

Radial fans are Working wheel placed in a spiral casing. Perhaps this type of hood is the quietest and most economical. In addition, centrifugal fans are unpretentious in operating conditions and easily cope with performance overloads.

On the pages of our online store, buyers can get acquainted with models from leading manufacturers bathroom hoods. Price for fans varies in a wide range, so buyers with any income can find suitable equipment here. For the convenience of visitors, the catalog is equipped with product filters, with which you can quickly select bathroom extractor. Buy the device is not difficult: just a few clicks, and you already own a fan, after which it remains only to wait for the delivery of your purchase. Delivery is carried out within the city Moscow and also to the regions.

Ventilation in the house is as important as heating or water supply. The hood in the bathroom is an integral part of the ventilation system. This issue must be approached very carefully, there are no unimportant details. In this article, we will analyze the basics of ventilation, select the right fan for the exhaust hood in the bathroom and carry out its installation.

Types of ventilation

Why do you need ventilation in the bathroom

Smart installation approach ventilation system in the house is the key to the health and quality of life of the family.

Among the prevailing opinions, there is an erroneous idea: the hood for the bathroom is not as significant as for other rooms in the house. Most people do not even think about the importance of ventilation for the bathroom and toilet. Others suggest that the windows will be enough for optimal air exchange. Of course, these ideas are fundamentally wrong.

The hood in the bathroom solves the problem of proper air exchange, therefore, there will be no unpleasant odors in the bathroom, and the air in the room will be fresh. This is especially true for a combined bathroom.

High humidity in the bathroom creates favorable conditions for the reproduction and growth of microorganisms. A properly functioning ventilation system will help to defeat rot and mold. Extractor in the bathroom helps to achieve optimum temperature and humidity, as well as maintain the parameters at the desired level.

The hood for the bathroom solves the following tasks:

creates air exchange;

maintains a microclimate.

Types of ventilation

There are two types of ventilation systems.

Natural exhaust in the bathroom is created by removing stale air through the ventilation shaft. This type of ventilation is laid down at the stage of designing and building houses. For the effective functioning of the system, an inflow is necessary. fresh air through special holes in the bathroom door.

Advice. In order to check how well the system works, you need to create a draft (open a door or window) and bring a sheet of paper to the ventilation grill - it should stick to it.

In cases where the bathroom hood does not work properly or is not efficient enough, forced ventilation in the bathroom can correct the situation.

Forced exhaust in the bathroom is created through the use of special devices - fans.

When is artificial ventilation necessary?

Artificial ventilation is necessary, with natural ventilation working properly, if you notice:

rust on pipes or metal products;

condensation on walls, windows, objects;

signs of appearance (black dots) or pronounced rot, mold.

Forced ventilation installed in the bathroom in addition to natural ventilation significantly reduces harmful effects high humidity. This has a positive effect on the condition and service life. household appliances installed in the room. It will allow you to keep the ceilings and walls in their original condition longer after the repair.

Fan classification

Bathroom fans are classified according to the following criteria:

at the location of the work item: overhead or channel. Overhead fans for the bathroom are mounted at the entrance to the ventilation shaft. Their installation is simple and affordable. The main work of duct fans takes place inside the duct ducts. Duct fans for the bathroom allow you to create a full-fledged ventilation system that combines several or all rooms in the house. The creation of such a system occurs during construction.
at the place of installation: ceiling, wall, roof. Ceiling, as a rule, these are duct fans, and wall - overhead. Roof fans are a whole complex supply and exhaust ventilation, which is placed under the roof of the house;

according to the principle of action: bladed, centrifugal. Bladed, in turn, are divided into axial and radial. The principle of operation of blade fans is to remove the exhaust air by rotating the blades or, in cases radial fan- with spatulas. Centrifugal hoods for toilets and bathrooms work by creating centrifugal force inside the fan;
by availability additional features: check valve for ventilation, hygrometer, switch-off timer, motion sensor. The hygrometer allows you to automatically turn on the hood in the bathroom at a given humidity parameter. The timer sets the time for the hood to turn off. The motion sensor starts the fan when a person enters the bathroom;
according to the method of inclusion: mechanical or automatic. Mechanical fans either have a separate on/off button or turn on with the light in the bathroom. Automatic fans turn on when the parameters are set, for example, when a person enters the room, the humidity exceeds the allowable value, the light switch is triggered.

The check valve for ventilation can be included with the fan or it can be bought separately.

The valve prevents the penetration of air back into the bathroom, which is important in the cold season. A plastic non-return valve for ventilation is required when channel system air duct so that odors from the kitchen or toilet do not penetrate into the bath.

How to choose the right fans for the toilet and bathroom

In order to choose a fan for the toilet and bathroom, you must set the desired parameters for its operation. First, it is worth calculating the required performance of the hood. To do this, the volume of the room *(multiply) by the number of air changes. For a combined bathroom and toilet, the value is 10, for a bathroom - 8. Further, if the number of people in the family is up to 3, * by 6, more than 3 - multiply by 8. It is recommended to buy bathroom fans with a performance margin, i.e. slightly more powerful than the result. The calculation of performance must be made for right choice fan. Otherwise, installing a weak hood will not produce the desired effect, and too powerful will lead to hypothermia of the room.

The noise figure is an important criterion when choosing a fan. During operation, the device creates two types of noise: due to moving blades or centrifugal force and due to system vibration. Noise at 35 - 40 dB starts to annoy nervous system person. To solve this problem, a silent bathroom fan is suitable - the volume of its operation is only 20-25 dB, for comparison, this is the volume of a whisper.

Silent bathroom exhaust fan has a number of design features, due to which the noise level is reduced. First of all, this is the presence of vibration isolators and a material of greater density, due to which the desired effect is achieved. The location of the fan and its type also affect the amount of noise. For example, a silent duct-type bathroom fan installed on the ceiling will create less noise already due to the fact that its system is located inside the duct.

Advice. When choosing a fan, you should consider models designed specifically for installation in the bathroom.

They have a high level of security. The design assumes protection against moisture and accidental splashes of water. In addition, they operate at reduced voltage. This characteristic plays an important role: in the event of a short circuit, voltages up to 25 volts will not lead to electric shock.

The toilet hood is similar in design to the bathroom hood. Distinctive features are lower power and fan diameter. If the average capacity of a bathroom fan is 100 m³/h, then the toilet hood can operate with a capacity of 50 m³/h.

When buying a fan, you should consider the following characteristics:

performance indicator;
noise indicator;
safety indicator.

Installing fans

Installing the hood in the bathroom, depending on the complexity of the system, can be carried out on your own or with the help of professional workers. Laying of channel ventilation is carried out at the construction stage.

Vane fans are the easiest to install, which is why they have become more widespread. It is enough to place the device under the grille of the ventilation system, connect it to electricity, hide the wires in an insulating box. When installing, consider the following points:

the hood for the toilet and bathroom is installed opposite the door, at the maximum height from the floor. Holes should be made in the bathroom door or a gap of 1.5-2 cm from the floor should be left;
installation of the hood is carried out only in a properly functioning ventilation shaft - only the grate is visible on the surface;
when installing ventilation in a private house, air must be vented outside, and not under the roof (for example, in the attic). Otherwise, condensation forms, which stimulates the development of rot. This is especially dangerous for wooden beams Houses;
a forced draft hood for the bathroom, having a ventilation check valve, is the preferred choice;
to reduce noise, you can use silicone sealant or silent fan models;
fastening is best done with self-tapping screws.

On what grounds should you choose a hood in the bathroom? How practical is a bathroom fan with a timer? How to properly install it in a room with a false ceiling? What should the connection of the device to the power supply look like? In this article I will try to answer these and many other questions.

Forced and natural

When is forced ventilation necessary?

Here are the signs that it's time for you to go to the store for the hood:

In the bathroom or bathroom between visits the water on the walls does not have time to dry;
Appeared on the ceiling or in the seams of the tiles fungus;

It can also be the result of periodic flooding by neighbors from above or malfunctions of plumbing equipment. Leaks of risers in the ceiling are especially insidious: there are no visible defects, and the ceiling of the lower apartment is constantly wet.

The air is constantly damp, musty;
Towels and clothes folded for washing smell like mildew.

To find out how effective natural ventilation is, a couple of simple tests will help:

Hold a piece of paper near the ventilation duct grille. During normal operation of the ventilation, it should be pressed against it by the air flow;

If this does not happen, repeat the experiment with a match or a lighter. If the flame brought to the ventilation duct does not deviate in its direction, the duct must be cleaned before installing forced ventilation.

Ventilators are on the staff of service organizations; All cleaning work is free for residents.. An exception is the case when the channel is clogged due to their fault (for example, construction debris during repairs).

Go shopping

Now - about how to choose a fan.

Performance

What should be the performance of the hood?

If it serves only a bathroom or a shared bathroom, performance is selected based on 7 - 9 cubic meters per hour per square meter area. So, for a bathroom with a typical Khrushchev area of 2.5 squares, the required minimum is 2.5 * 7 \u003d 17.5 m3 / hour.

In practice, the performance of fans with an impeller diameter of 100 mm usually starts from 50 - 80 m3 / h. This allows, if necessary, to adjust the speed by dimming the device while maintaining an acceptable quality of ventilation. However, I will touch on the topic of connection in a separate section.

In Soviet-built houses, the ventilation scheme is more typical, in which all air exchange in the apartment is carried out only through ventilation ducts in the bathroom and in the kitchen. Air flow is provided by gaps in wooden frames.

supply plastic windows supply valves;

Provide forced air exchange taking into account the area of \u200b\u200bresidential premises. For rooms, the air exchange rate is 3 cubic meters per hour per square meter. The required performance can be distributed to all ventilation ducts - in the bathroom, in the toilet and in the kitchen.

Installation method

Which fan to install - overhead or duct?

The invoice is practical in the following situations:

It is installed instead of the ventilation duct grille directly on the wall;
It is placed in a false ceiling, the design of which prevents air from escaping through the slots(eg drywall).

If the ceiling is assembled from panels or rails, a duct fan installed directly in the ventilation duct or in the exhaust pipe is preferable. AT false ceiling the hatch is mounted for its maintenance and replacement.

In the photo - a hatch for access to the duct fan in the false ceiling of my attic.

Basic Functions

What to look for Special attention at the time of buying?

To the noise level. Silent operation is ensured by:

Plain bearing. Unlike rolling bearings (roller or ball), it does not rattle when the impeller rotates;

The bearing sleeve must be bronze. The steel bushing will quickly develop play, which will increase the noise level.

Round shape blades. Square or pointed blades are noisy at high speeds;
Small angle of attack of the blades;
Closed impeller. Air is sucked in through a hole opposite its center or through a slot on the sides.

Additional functions

What additional features can hoods be equipped with?

Here short list options:

Autonomous food. The fan is capable of running on batteries or from a built-in battery that is charged from the mains. Autonomy will be very helpful with frequent power outages or in country houses;
The bathroom fan with humidity sensor turns on when the humidity threshold is exceeded. It will work for some time after taking a shower and turn off on its own, without creating unnecessary noise and saving electricity;

The timer will allow the hood to turn off some time after turning off the light in the bathroom. Of course, it will only work if the fan and light are powered through a common switch;
The check valve will eliminate the occurrence of reverse thrust in windy weather. It ensures that your bathroom will not be saturated with aromas from neighboring apartments;

A low-voltage hood powered by 12 volts will come in handy in LED bathrooms. Both it and the fan are powered through a common power supply, outside the bathroom. Such a circuit guarantees your safety: even with a short circuit, you will not receive an electric shock.

Captain Evidence reminds: the choice of a fan with an abundance of additional functions is not always justified. The more complex the device, the higher its price and lower reliability.

Let's start installation

into the wall

How to install an overhead fan in a horizontal ventilation duct?

Installation is carried out on galvanized self-tapping screws with a length of at least 60 mm. They are screwed into plastic dowels inserted into holes drilled in the wall around the ventilation duct. Grooves for fasteners can be seen on the hood body, under the removable front panel.

The oblong grooves are more practical as they allow the fan to be level after the holes have been drilled in the wall.

After installing the fan the gaps between its front panel and the wall are sealed acrylic putty. It will prevent exhaust air from entering the room. The elasticity of the acrylic will allow the seam to withstand the inevitable vibration of the fan.

To the ceiling

How is installation carried out in the case of a false ceiling?

The hood body is attached to the Molly dowels through holes pre-drilled in the gypsum board or other material. When tightening the fastener, its shell creates back side the ceiling is a reliable stop with a large area.

How to fix a ceiling fan in case of a stretch ceiling?

The socket of a rigidly fixed ventilation pipe is brought to the ceiling level. Opposite the socket, a cutout is marked in the canvas of the stretch ceiling; then a reinforcing ring is glued onto it, after which the canvas inside the ring is cut out. The overhead hood is inserted into the socket on the silicone sealant.

Nuance: it is much more reasonable to provide a ventilation duct with a duct fan, and a canvas with a ventilation grill. Ideally, the space above a hanging or stretch ceiling should be ventilated. Otherwise, high humidity will quickly lead to the appearance of fungus on the ceiling and walls.

How is the do-it-yourself installation carried out in the case of a duct fan and a plastic ventilation duct?

The fan is placed in the socket of the pipe, after which it is fixed in it with a second tightly inserted pipe. I used for ducted 100mm fan sewer pipe with a diameter of 110 mm and a compensating branch pipe.

The hood is planted in a compensator on silicone and fixed in it with a pipe. The power wire is brought out through a hole drilled in the compensator with a diameter of 6 millimeters.

Private house

How to bring a ventilation duct to the street in a private house?

I made it through bearing wall on the first floor and through the gable under the overhang on the attic. The ventilation outlet is equipped with a corner and an umbrella-deflector. The deflector prevents water from entering the ventilation system in rain and oblique wind, and also further enhances traction in windy weather.

Electricity

What could be the most simple circuit exhaust connection?

The simplest option is to connect through a switch that is common to the fan and bathroom lighting. The wire is thrown directly from the light bulb socket. The main disadvantage of such a scheme is that the hood is idle for most of the day, while the bathroom needs ventilation all the time.

How to connect the fan in the bathroom to the switch, ensuring its operation independent of lighting?

Very simple: using a two-gang switch. Zero wire- common for light and ventilation; the phase is hung up on different buttons. In my opinion, this scheme is the most practical.

The most sensible solution is to connect ventilation to a separate switch key.

Can ventilation performance be adjusted?

Yes. I used a regular incandescent dimmer for this purpose. Periodically met by me on thematic forums, statements that some special dimmers are needed for fans - clean water fairy tales: the lighting dimmer works great with any range hood.

Dimming allows you to flexibly adjust the fan speed, choosing between the maximum volume of pumped air and silence.

If the mirrors and walls in the bathroom constantly fog up, the air is stale, and mold appears every now and then in the corners, this means that natural ventilation cannot cope with its task. Solving this problem is simple - you need to install an exhaust fan. The choice of modern exhaust devices is very wide - from the simplest to silent models with timers and sensors. To ensure the most efficient air exchange in the room, you need to know by what criteria it is worth choosing fans and how to install them correctly.

The design of the exhaust fan is quite simple: housing, motor, impeller with blades. There are models equipped check valve, which does not allow foreign odors from other apartments to enter the room, which is very important for high-rise buildings.

The air duct of the exhaust device is connected to the general ventilation system or is output separately through the wall to the outside. According to the mounting method, all exhaust fans are divided into ceiling and wall, as well as built-in and overhead.

Ceiling ones are less in demand, although they are distinguished by high performance and simple installation. Such a fan is able to actively circulate a large volume of air, so it is great for spacious bathrooms. But most consumers still choose wall-mounted models, both built-in and overhead. They are easy to install, easy to use, easy to clean and replace. Thanks to its compact size and modern design cases, they look quite aesthetically pleasing, fitting perfectly into any interiors.

Depending on the internal device, fans are divided into:

electrical– simple models with built-in or external switch. That is, the residents of the apartment must independently turn the device on and off as needed. A very common option is when such a fan is connected to a general switch in the bathroom, and then the hood turns on simultaneously with the lamps. True, in this case, moisture does not always have time to completely go into the ventilation, but electricity consumption is reduced;
automatic- exhaust devices equipped with special sensors. Models with humidity sensors automatically turn on as soon as the moisture level exceeds the norm, and turn off when the condensate has completely evaporated. Models with motion sensors turn on when a person appears and turn off when the room is empty. There are also automatic fans with timers that operate only for a predetermined interval of time.

Exhaust fans are also classified according to the type of construction. In the domestic sphere, the most popular are axial and channel devices that are suitable for multi-storey and private houses.

In axial fans, the movement of air occurs along the axis of rotation of the blades, which is the reason for such a name. The design is very simple: a body (usually cylindrical), an impeller with blades, an electric motor. Many models have a front-mounted manifold that improves aerodynamic properties. The structure of the blades reduces the resistance to air flow, so the fan has a high efficiency. According to the type of installation, such devices can be both wall-mounted and ceiling-mounted.

Most modern axial fans are characterized by low power consumption and reduced noise levels, unlike previous generation models. They can work for a long time without stopping, are easy to clean, and have an attractive design. For these devices to be effective, the length of the air duct should not exceed 4 m. The same applies to the area of \u200b\u200bthe bathroom - the smaller the room, the more efficient the hood.

axial exhaust fan

Duct fans

For bathrooms of a large area, ducted or centrifugal fans are best suited. Their design differs markedly from axial devices: inside the cylindrical body there is a drum with many narrow curved blades. With the help of centrifugal force generated by the blades during rotation, the air is drawn inward and directed to the ventilation duct.

Such fans work effectively with air ducts with a length of 4 meters or more, they are installed both on the ceiling and on the wall (depending on the modification). The extraction can be carried out continuously, but usually the device is connected to a switch in the bathroom or to a humidistat. This saves energy and extends the life of the fan. Many models are designed for concealed installation and are relatively quiet, so that they are almost invisible in the bathroom.

Advantages and disadvantages

If you still doubt the advisability of installing such fans in the bathroom, it would be useful to familiarize yourself with the advantages of exhaust devices:

condensation will no longer accumulate on walls and other surfaces, dampness will leave the room;
installation will not require much effort and time, even a beginner can cope with it;
modern models of fans are very compact, so they are suitable for even the smallest bathrooms;
thanks to modern design and discreet design, exhaust fans will harmoniously fit into any style of interior;
most models are equipped with a protective mesh, which eliminates the ingress of insects and small objects inside the case, which means that you will have to clean the device less often;
the front panel can be easily removed for fan maintenance - cleaning the blades and lubricating the motor.

As for the shortcomings, there are very few of them:

fans cannot work absolutely silently, and their buzz can annoy some consumers;
electricity consumption increases, albeit slightly;
device requires regular cleaning and lubricants for normal operation.

Also, a lot depends on the correct installation: if the fan is not positioned correctly, the air circulation is disturbed, and there is nothing to say about a high-quality hood.

Exhaust fan selection rules

So, if the decision to buy a fan is made, you need to choose the right model so as not to be disappointed later. You need to choose at once according to several parameters - performance, safety, noise level and, of course, in terms of quality-price ratio.

Performance

This criterion is the main one, because the efficiency of air exchange depends on it. Here it is important to choose the right power of the device relative to the area, since the same fan gives a different result in a small and large bathroom. According to building codes, the air exchange rate for a bathroom is 6-8 units, that is, in an hour the entire volume of air in the room should change from 6 to 8 times. As a rule, if no more than three people use the bathroom, they choose a multiplicity of 6, if more than three - a multiplicity of 8. The calculations are not difficult to perform: you need to find the volume of the room and multiply it by the air exchange rate.

For example: there is a bathroom with dimensions of 1.9x1.7 m and a height of 2.65 m, 3 people use it. We calculate the volume of the room - 1.9x1.7x2.65 \u003d 8.56 m. Round up to 9 and multiply by the multiplicity - 9x6 \u003d 54 m3.

It turns out that for such a bathroom the best choice there will be a device with a capacity of 54 m3 / h. Of course, it is not always possible to find a model that best matches the calculated parameters, so you can choose a fan with a small margin of performance.

Security

Fans are available for bathrooms and toilets. additional protection electrical contacts from moisture, which must be indicated in the instructions and on the packaging. If you put an ordinary model, and water gets into it, this can cause a short circuit and even a fire, so you can’t risk it in any case.

Now you can find low-voltage extractors specifically designed for bathrooms and saunas. They have moisture and thermal protection, and can work effectively at 100% humidity and high temperatures. True, the cost of such fans is higher, and they cannot be connected to a conventional electrical network, which entails additional costs, but the safety of the residents is worth it.

Noise level

The noise produced by the fan should not exceed 30 dB, otherwise it will irritate the household. If you plan to turn on the fan at night, choose a model with a noise level of up to 25 dB. The lower this indicator, the more comfortable you will be in the bathroom with the hood turned on. This is especially true for those whose fan runs continuously.

As for the quality of fans, it is better to focus on well-known trade brands, whose products have already been tested by time. For example, household fans of the brand Soler & Palau (Spain), VENTS (Ukraine), Electrolux (Sweden) have a lot of positive reviews.

These companies value their reputation, so their products are of high build quality and durability. The main thing is to buy fans in specialized stores, where they can present an appropriate certificate for the product and issue a warranty card. So you avoid the risk of buying a cheap fake, not branded equipment.

How to install an exhaust fan yourself

Exhaust fans - photo

The process of installing the fan itself takes a minimum of time, but before that you need to properly prepare everything, think over the connection method, and, if necessary, lay a cable for power supply. All wiring should be located in strobes and hidden under the cladding to eliminate the slightest risk of contact with water. If the fan is ceiling, and the ceiling itself is suspended, then there is no need for strobes: the wiring is attached directly to the ceiling, fixed with special clamps. Of course, all wires must be in the corrugation.

To connect the fan, a three-core VVG cable is usually used - it allows you to supply zero, ground and phase to the device from the switch.

Moreover, the switch can be either single-key or two-key. The second option is preferable: you can turn the fan on and off regardless of the light.

If you do not have experience with electrical wiring, you should invite a professional electrician for this, because any mistake or negligence can lead to serious consequences. After the cable is laid, you can proceed with the installation of the fan.

For work you will need:

Bulgarian;
drill with drills for tiles and concrete;
pencil;
connecting terminals;
regular and indicator screwdrivers.

Step 1. Unpack the fan, check its integrity and completeness. Usually fasteners are included, but if they are missing, you should buy self-tapping screws and plastic dowels in advance.

Step 2 Prepare the vent. If it was covered with a cladding, you need to attach the fan housing to the tile and carefully circle it with a pencil. After that, a cut is made along the contour with the help of a grinder. If the hole was open, you need to clean it of dust and construction debris, make sure that the fan enters well and does not cling to the edges.

Step 3 Remove the front panel and the inner cover of the fan from the device, put them aside. Now you need to mark up the fasteners. To do this, the fan is inserted into the hole until it stops, aligned, guided by the seams of the tile or the building level, and points are marked with a pencil through the holes in the case.

If the fan has a rope-switch, you need to dismantle it

Step 4. A drill with a victorious tip is inserted into the drill and carefully, at low speeds, drill through the tile at the marked points. Then they change the drill and, in the hammer drill mode, they go deep into the concrete. The finished holes are cleaned of dust and plastic dowels are inserted into them.

Step 5 Once again try on the fan to the hole and determine where the cable will pass. In this place, a semicircular groove is cut out with a grinder, corresponding in size to the cross section of the wire. A hole for the wire is also drilled on the body of the device.

Step 6 The fan is brought to the wall, an electric wire is threaded through the hole in the case, then it is inserted into the groove and the fan is inserted. Fix it to the wall with self-tapping screws using a screwdriver or screwdriver.

Screw for fixing the fan

Advice. In order not to drill the wall, you can fix the fan with silicone sealant. The device weighs a little, moreover, it is partially held by the wall, so such a mount is quite enough. The main thing is that the sealant is of high quality and waterproof.
Sealing wiring

Step 8 Close the fan with a lid, which is screwed in the center with one screw, and then turn on the power and check the operation of the device. Now it remains only to insert the protective grid and secure the front panel. Many masters prefer to do without a mesh, as it quickly becomes dirty and stops passing air. To avoid this, you have to regularly remove it and rinse with water.

Fixing the decorative cover with a bolt

This completes the installation of the fan. In the process of use, you will have to clean the ventilation grille and blades from accumulated dust from time to time. If, after cleaning, the hood works poorly, this indicates that the exhaust channel is clogged. AT apartment buildings It is impossible to fix such a problem on your own and you need to call a specialist. But in a private dwelling, it is much easier to clean the ventilation system, so many homeowners do it on their own.

The hood to the toilet with a fan today is already considered a necessity, and not a whim of the residents. With its help, unpleasant odors are removed, and the freshness in the room is also preserved. But in order for the system to work effectively, first of all, you need to correctly select the required power, as well as install it taking into account all requirements.

Features of choice

When choosing a device, it is necessary to pay special attention to both safety during operation and efficiency. Both parameters are key.

If the installation is carried out on your own, then you need to learn well design features fan for toilet and bathroom. This will allow you to choose perfect option for specific space and needs.

It's important to exclude salespeople's advice from the hardware store for some reason. This is due to their narrow knowledge in the field of installation and installation of ventilation, which is limited to the assortment of the store. In addition, they often want to sell stale goods on the shelves, so giving good advice do not intend.

Installation of an exhaust fan. How to do.

In this regard, you need to choose a fan yourself. To make the right choice, you first need to know what types of such devices are. There are 2 main types:

Mounting methods

It is important to remember that the installation of a fan in the bathroom must be carried out during repair work, otherwise the finish will be damaged. In addition, you need to decide which option will be more convenient for installation - channel or invoice.

Both the first and the second have their pros and cons:

A common problem is the distribution unpleasant odors from the lower floors of the house. To prevent this situation, it is recommended to use a hood with a valve for the toilet. It works on a simple principle. If the fan is not turned on, then a thin damper (valve) closes it. When the blades begin to spin, the air flow bends the damper and pulls the air out of the room. When you stop again, the valve closes again and prevents excess odors from entering the room.

Specifications

When the design type is selected, you can go shopping at a specialized equipment store. It is important to choose a high-quality and reliable model.

One of the necessary specifications when choosing is the diameter of the device. These details must be known prior to purchase. If the model is slightly smaller than the desired cavity width, then there is nothing to worry about. And if on the contrary - more, then you will have to do additional work to prepare the place for installation.

Performance should be enough for the full operation of the ventilation system. To be specific, then in 1 hour, the device should pump up to 8-9 volumes of the room. Due to the fact that the area of the bathroom is usually small, it makes no sense to buy fans with too much power.

Production material - plastic. Household fans for bathrooms and toilets are made from polymers. This is due to the cheapness of production. But do not think that plastic equipment will not have sufficient strength. Modern production is at a fairly high level technically. The only thing worth paying attention to is the quality. good products will not have uneven seams, surfaces, flaws, etc.

The volume of work must also be taken into account. It should be no more than 35 dB. Although today it is very rare to find such models. Typically, most products good producers make virtually no noise.

The fan mount can be selected from two possible options - on bearings or bushings. The bearing option is better, since the device will work much longer.
